How Do I Weight the final grade based on Assignment Groups
From e-Learning Documentation
You can weight final grades based on the Assignment Groups weights.
Open Assignments

Click the Weight final grade based on assignment groups checkbox.
Set Weights
Enter the percentage weights for each of the different Assignment Groups you created. The percentage weights you specify here will determine how Canvas calculates the final grade for your course. These percentages can be changed at any time and students will be notified when any changes are made. The weights will show up in the Gradebook for both students and instructors.
Click the Save button when you are finished.
